said means comprising preferably a pin 11 borne by flange 5 of ring 1and extending substantially across'groove 7, said pin 11 beingpreferably located opposite transverse slit 3 of ring 1, but may belocated at any other desired distance from said split 3. Said pin 11extending across groove '7,'as described, crosses the plain ofcircumferential movement of tongue 8 or parts 'adjacent thereto in saidgroove 7, and, when ring 2 is so placed upon ring 1 that the edgesformed by split' l and said-tongue or parts adjacent thereto areadjacent toropposite sides of said pin 11, said pin will hold gapsformed in rings 1 and 2 by cuts 3 and 4, respectively, apart from eachother and thus will prevent them from coinciding to break thesubstantial continuity of the device as a leak-proof packing ring.

Various changesin the details of constructionand arrangement of partsmay be made without departing from the-nature and spirit of thisinvention.

I claim:

A packing ring comprising a transversely split base-ring, bearing a pairofflanges of relatively greater and less depth, said flanges beingadapted to form a peripheral groove inthe outer surface of saidbase-ring,

a second transversely split ring bearing a member depending from itsinner g'surlace and, also, bearing a lateral extension, said second ringwith its depending inember and face with the upper edge o1 the deeper ofsaid flanges, and means borne by said basering adapted to maintain thegap formed by the transverse split in the second ring, and the ap formedby the transverse split in the ase-ring in spaced relation to eachother, comprising a pin borne by the flange of the first-mentioned ringand extending substantially across the peripheral groove, whereby thecircumferential ir-otion of the second mentioned ring is prevented.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses. FRANK SIMONS. Witnesses:
